BACKGROUND ART

Chemokine is known as a basic protein which has chemotaxis and an activating effect on endogenous leucocytes and also has strong heparin-binding abilities. It is now considered that chemokine is associated with not only control of infiltration of specific leucocytes upon inflammatory and immune responses, but also development, homing of lymphocytes under physiological conditions and migration of hemocyte precursor cells and somatic cells.

Differentiation, proliferation and cell death of blood cells are controlled by various cytokines. Inflammation occurs at a local region in a living body. Differentiation and maturation of lymphocytes, and the like are carried out at a specific site. More particularly, required various cells migrate and accumulate in the specific site and a sequence of inflammatory and immune responses arise. Thus, as well as differentiation, proliferation and death of cells, cell migration is also an essential phenomenon to an immune system.

In the living body, migration of blood cells start with shifting hemopoiesis that started at AGM (Aorta Gonad Mesonephros) region via fetal liver to permanent hematopoiesis at bone marrow in a development course. Moreover, precursors of T cells and thymus dendritic cells migrate from fetal liver into bone marrow and then into the thymus gland. They differentiate under thymus environment. The T cells are subjected to clonal selection migrates into secondary lymphoid tissues, where they contribute to immune responses in periphery. Skin Langerhans cells that caught antigen, thereby undergone activation and differentiation migrate to T cell region in a topical lymph node, where they activate naive T cells therein as dendritic cells. The memory T cells again perform its homing into the lymph node via lymphatic and blood vessels. In addition, B cells, T cells in intestinal epithelia, γδT cells, NKT cells, and dendritic cells migrate from bone marrow not via thymus, differentiate and contribute to immune responses.

Chemokine is very involved in these various cell migrations. For example, SDF-1 (Stromal cell derived factor-1) and its receptor, CXCR4 also act on various immune- and inflammatory reactions. For example, they have been reported to be associated with accumulation and activation of CD4+ T cells in a synovial membrane from a human patient suffering from rheumatoid arthritis (J. Immunol., 165, 6590-6598 (2000)). In addition, in a CIA model mouse, CXCR4 inhibitor inhibited accumulation of leucocytes in a joint and dramatically reduced arthritis score (J. Immunol., 167, 4648-4692 (2001)). In a mouse OVA-induced airway hypersensitive model, an anti-CXCR4 antibody reduced the number of eosinophiles accumulating in pulmonary interstitial tissues and prevented airway hypersensitivity (J. Immunol., 165, 499-508 (2000)).

There has been reported that SDF-1 and its receptor, CXCR4 play an important role in maintaining hemopoietic stem cells in bone marrow J. Exp. Med., 185, 111-120 (1997), Blood, 97, 3354-3360 (2001)). Accordingly, control of SDF-1 and CXCR4 is expected to modulate recruitment of hemopoietic stem cells to peripheral blood and is useful for peripheral blood stem cell transplantation and reproduction transplantation treatment.

SDF-1 and CXCR4 are associated with infiltration of various cancer cells such as breast cancer, prostate cancer, and ovarian cancer (Nature, 410, 50-56 (2001), Cancer Res., 62, 1832-1837 (2002), Cancer Res., 62, 5930-5938 (2002)). In a model of a SCID mouse which is transferred a human breast cancer cell strain into, an anti-CXCR4 antibody prevented metastasis of breast cancer cells to lung (Nature, 410, 50-56 (2001)). In human ovarian epithelial tumor, highly expression of SDF-1 promotes accumulation of plasmacytoid dendritic cells and inhibits the act of bone marrow dendritic cells associated with tumor immune and suppresses tumor immune (Nat. Med., 12, 1339 (2001)). Moreover, SDF-1 is associated with proliferation and migration of non-Hodgkin's lymphoma cells, and in a model of a NOD/SCID mouse which is transferred a human non-Hodgkin's lymphoma cells into, an anti-CXCR4 antibody inhibited proliferation of the tumor cells and improved mouse mortality (Cancer Res., 62, 3106-3112 (2002)).

SDF-1 and CXCR4 play an important role for formation of hippocampus dentate gyrus granulocyte, that is essential for memory and learning and are associated with development of a disease associated with adult plasticity and pathology of hippocampus, for example Alzheimer's disease, stroke and epilepsy (Development, 129, 4249-4260 (2002), Trends in Neuroscience, 25, 548-549 (2002)).

SDF-1 and CXCR4 are essential for a function of self-reactive B cells associated with development of diabetes. In NOD mouse, an anti-SDF-1 antibody reduced blood glucose level and the number of mature IgM-FB cells in a periphery tissue (Immunology, 107, 222-232 (2002)). In a human arteriosclerotic plaque, SDF-1 was highly expressed and activated blood platelets (Circ. Res., 86, 131-138 (2000)).

SDF-1 and CXCR4 are involved in residence of hemopoietic stem cells and hemopoietic precursor cells in bone marrow. CXCR4 antagonist, AMD 3100 in combination with G-CSF increased the numbers of hemopoietic stem cells and hemopoietic precursor cells in periphery blood (Journal Experimental Medicine, 2001, 1307-1318 (2005)).

In addition, the results of SDF-1/CXCR4 knock-out mice showed that SDF-1 is essential for functions of central nervous system, heart and vessels of gastrointestinal tract in addition to lymphocytes (Nature, 382, 635-639 (1996), Nature, 393, 591-594 (1998), Nature, 393, 595-599 (1998)). Accordingly, it may be associated with a disease of these tissues.

Thus, chemokine receptors are expressed at various specific cells and at a specific time. They are largely associated with the control of inflammatory- and immune-responses through a mechanism by which their effector cells accumulate in a site where chemokine is produced.

Acquired immunodeficiency syndrome (also called AIDS) that caused by infection of human immunodeficiency virus (hereinafter abbreviated to HIV) is one of diseases for which therapies are the most eagerly desired lately. Once HIV infection has been established in a main target cell, CD4+ cell, HIV repetitively proliferates in a patient's body and in the event deathly destroys T cells responsible for immunological functions by necrosis. In this process, immunological functions are gradually deteriorated, various immunocompromised states become to develop such as fever, diarrhea and swelling of a lymph node, and various opportunistic infections such as carinii pneumonia are easily complicated. It is well known that such a state is the onset of AIDS and induces malignant tumors such as Kaposi's sarcoma and becomes severe.

Currently, various preventive and therapeutic treatments for AIDS are tried as follows: for example, (1) inhibition of HIV proliferation by administration of reverse transcriptase inhibitors and protease inhibitors, and (2) prevention or alleviation of opportunistic infections by administration of an immunostimulant, etc.

HIV mainly infects helper T cells which play a key role in the immune system. Since 1985, it has been known that in this process HIV utilizes a membrane protein CD4 that is expressed on the membrane of T cells (Cell, 52, 631 (1985)). CD4 molecule consists of 433 amino acid residues and is expressed in macrophages, some B cells, vascular endothelial cells, Langerhans cells in skin tissues, dendritic cells located in lymphatic tissues, glia cells of central nervous system and the like in addition to mature helper T cells. However, as it becomes obvious that HIV infection cannot be established with only CD4 molecule, the possible presence of some factor that is responsible for infection of cell with HIV, other than CD4 molecule, has been suggested.

In 1996, a cell membrane protein called Fusin has been identified as a factor responsible for HIV infection other than a CD4 molecule (Science, 272, 872 (1996)). This Fusin molecule has been demonstrated to be a receptor for SDF-1, namely, CXCR4. In addition, it has been shown that SDF-1 specifically inhibits infection of T cell-directed (X4) HIV in vitro (Nature, 382, 829 (1996), Nature, 382, 833 (1996)). This may be considered that SDF-1 binds to CXCR4 prior to HIV, thereby taking away a scaffold for infecting a cell from HIV resulting in inhibition of HIV infection.

Also, at the same period, there has been found that another chemokine receptor CCR5, that is a receptor for RANTES, MIP-1α, and MIP-1β, is utilized at infection of macrophage-directed (R5) HIV (Science, 272, 1955 (1996)).

Accordingly, those which can compete with HIV for CXCR4 and CCR5 or those which bind to a HIV virus and prevent for said virus from binding to CXCR4 and CCR5 may be a HIV infection inhibitor. In addition, there is a case where a low molecular weight compound discovered as a HIV infection inhibitor was showed to be indeed an antagonist of CXCR4 (Nature Medicine, 4, 72 (1998)).

As described above, compounds having an antagonistic activity against CXCR4 is effective, such as, for prevention and/or treatment of inflammatory and immune diseases, allergic diseases, infections (particularly HIV infection), and diseases associated with the infection, psychoneurotic diseases, cerebral diseases, cardiovascular diseases, metabolic diseases, cancerous diseases and the like. Also, the compounds are useful for cell medical treatment and regeneration therapy.

(iv) Evaluation of the Influence of a Compound of the Present Invention on Blood Pressure and Heart Rate

A rat is anesthetized with urethane (1.2 g/kg subcutaneous administration). After neck midline dissection, a catheter for measuring blood pressure is inserted into a right common carotid artery. Then, after dissecting inguinal region, a catheter for chemical injection is inserted into a femoral vein and fixed. A catheter for measurement of blood pressure is connected to a pressure transducer and then the pressure waveform is recorded on a thermal writing pen recorder through an amplifier for strain compression (AP-641G (manufactured by NIHON KOHDEN CORPORATION)). In this case, regarding a heart rate, a value through an cardiotachometer (AT-601G (manufactured by NIHON KOHDEN CORPORATION)) using the pressure waveform obtained from the amplifier for strain compression as a trigger is recorded on a thermal writing pen recorder. The test compound is dissolved in a 10% solubilizing agent/physiological saline solution (volume ratio of polyoxyethylene hydroxystearate:propylene glycol:physiological saline=7:3:190) so as to adjust the concentration to 0.1, 0.3, 1, 3 or 10 mg/mL to prepare solutions. Each solution is intravenous administered at 1 mL/Kg through the caudal vein over about 10 seconds. Accumulative administration of stepwise increasing in dosage is carried out to an individual.

BIOLOGICAL EXAMPLES

Efficacy of the compound of the present invention, for example the fact that the compound of the present invention has CXCR4 antagonistic activity, has been demonstrated by the following experiment.

A measuring method of the present invention was modified to improve accuracy and/or sensitivity of the measurement for evaluating the compound of the present invention. The detailed experimental methods are shown bellow.

As mentioned above, a more direct procedure is a screening a compound that prevents for HIV from binding to CXCR4, which is a receptor on CD4+cell, on an assay system using HIV viruses. However, using HIV viruses for a large-scale screening is not practical due to its difficult handling. On the other hand, both of T cell-directed (X4) HIV-1 and SDF-1 bind to CXCR4 and therefore CXCR4 binding sites at both of HIV-side and SDF-1-side as well as SDF-1- and HIV-binding sites at the CXCR4 side may presumably have any common characteristics. Thus, to find a compound inhibiting absorption of HIV viruses to a cell that is a different mechanism from those of pre-existing anti-AIDS drugs (reverse transcriptase inhibitors and protease inhibitors), an assay system using an endogenous ligand for CXCR4, SDF-1 instead of HIV may be available.

Specifically, as a system of screening a compound that inhibits the binding between SDF-1 and CXCR4, for example a system of measuring the binding between iodine-labeled SDF-1 and a human T cell strain in which CXCR4 is known to be expressed is operable. The identical idea is possible since macrophage (R5) HIV and RANTES, MIP-1α, and MIP-1β all bind to CCR5.

TEST METHODS Test Example 1 Study for Inhibition of Binding Human SDF-1 to OEM Cells

To human T cell strain OEM cells in a binding buffer (containing HEPES and BSA), the test compound and ¹²⁵I-SDF-1 (NEN) were added and the mixture was incubated at 4° C. for 60 minutes. The reacted OEM cells were rapidly filtrated with a GF/B membrane filter plate (Packard) to adsorb. The plate was washed with PBS three times and then dried. Microscint+20 (Packard) was added thereto. An amount of the radioactivity bound to the OEM cells was measured using Top Count (Packard) and inhibition (%) of the test compound was calcurated according to the following equation: Inhibition={(Et−Ea)/(Et−Ec)}×100

wherein

Et: amount of radioactivity when the test compound is not added,

Ec: amount of radioactivity when non-radioactive SDF-1 (Pepro Tech) is added in an amount of 1000 times as much as ¹²⁵I-SDF-1 as a test compound, and

Ea: amount of radioactivity when the test compound is added.

All compounds of the present invention shown in the Example exhibited inhibition of 50% or more in a concentration of 10 μM. For example, IC₅₀ value for compound 14 was 11 nM.
